Event Details

You have 24h to create your game start and finnish before end of October.

🤔 Designers can spend as much time thinking about a game design as they want, but cannot begin creating (or even physically sketching) until…
🟢 When a designer is ready to start putting pen on paper, they announce their start time on this challenge thread for the bi-month by posting that they are starting
⏲️ From that exact moment, that designer has 24 hours to complete their design, editing their intro post with the game details
🛑 As soon as 24 hours have expired, that designer may not touch their content until the challenge is complete (at the end of the bi-month)
